Rana tigrina were reared from hatching to metamorphosis in aquaria containing different depths but equal volume of water. To exchange atmospheric air, tadpoles in the shallow aquarium surfaced less frequently, travelled shorter distance at less metabolic energy cost and hence grew larger (3.1 g) at a higher (25%) efficiency than those (2.5 g; 19% efficiency… CONTINUE READING
